Capability comparison
| Concern | E2B | Daytona |
|---|---|---|
| Provider value | e2b | daytona |
| Image | The image field is interpreted as an E2B template ID. It defaults to base when omitted. | The image field is a container image. The adapter generates a one-line Dockerfile using that image. |
| Lifetime | The timeout is a sandbox lifetime in seconds and defaults to 300 when omitted. | The API accepts seconds and the adapter rounds them up to whole Daytona TTL minutes. |
| Command output | The adapter preserves separate stdout and stderr streams and returns the command exit code. | Daytona returns combined command output. The adapter places it in stdout and returns an empty stderr. |
| Credential | E2B API key | Daytona API key |
One create endpoint, explicit provider input
The endpoint and authentication boundary are shared. The request body changes only where the selected provider's supported creation inputs differ.

- The create, get, runCommand, and delete methods across generated SDKs.
- Normalized sandbox IDs, provider values, status, and metadata.
- Command, working-directory, and environment inputs for execution.
- Normalized stdout, stderr, and exitCode response fields.
What is not automatically portable
Existing sandbox state is not transferred between E2B and Daytona. An ID stays bound to the provider selected at creation. Images and lifetimes also retain the semantics shown above.
Current limitations
E2B
- The image value is a template ID, not a general container image.
- The sandbox remains attached to E2B for its complete lifecycle.
- Wildflower Computer does not migrate E2B filesystem state to another provider.
Daytona
- Timeout precision is one minute after adapter rounding.
- Standard output and standard error are not separable in the synchronous Daytona command response.
- The sandbox remains attached to Daytona for its complete lifecycle.
